<p>This section covers the rendering capabilities of HiAPI, focusing on how to create and display visual content in your applications.</p>
<h2 id="overview">Overview</h2>
<p>HiAPI provides a powerful rendering system built around the <a class="xref" href="../../../../api/Hi.Disp.DispEngine.html">DispEngine</a> and <a class="xref" href="../../../../api/Hi.Disp.IDisplayee.html">IDisplayee</a> interface. This system enables you to:</p>
<ul>
<li>Create and render 3D and 2D graphics</li>
<li>Implement interactive user interfaces</li>
<li>Achieve high-performance rendering across multiple platforms</li>
<li>Handle touch, mouse, and keyboard input uniformly</li>
</ul>
<h2 id="key-components">Key Components</h2>
<p>The HiAPI rendering system consists of several key components:</p>
<ul>
<li><strong>DispEngine</strong>: The core rendering engine that processes displayees and handles user interaction</li>
<li><strong>IDisplayee</strong>: The interface for renderable objects</li>
<li><strong>Drawing</strong>: A fundamental rendering unit for creating basic geometric elements</li>
<li><strong>RenderingCanvas</strong>: UI controls for different frameworks that host the DispEngine</li>
</ul>

<h2 id="basic-rendering-workflow">Basic Rendering Workflow</h2>
<p>The typical workflow for rendering with HiAPI follows these steps:</p>
<ol>
<li><strong>Create Displayees</strong>: Implement <a class="xref" href="../../../../api/Hi.Disp.IDisplayee.html">IDisplayee</a> or use existing implementations like <a class="xref" href="../../../../api/Hi.Disp.Drawing.html">Drawing</a></li>
<li><strong>Configure DispEngine</strong>: Create and initialize a <a class="xref" href="../../../../api/Hi.Disp.DispEngine.html">DispEngine</a> with your displayees</li>
<li><strong>UI Integration</strong>: Use RenderingCanvas components to display the rendered content in your UI</li>
<li><strong>Handle Input</strong>: Process user interactions through the DispEngine's input handling methods</li>
</ol>
<p>This pattern works consistently across all supported UI frameworks, allowing you to develop cross-platform applications with a unified codebase.</p>
